Electric vaporizing attachment



Uct. 15, 1929. E. KOSANEK ELECTRIC VAPORIZING ATTACHMENT Filed April 5,1928 Enoeutoz [570/ fibsaimd Magnum Patented Oct. 15, 1929 UNITED STATESPATENT OFFICE ELECTRIC VAPORIZING ATTACHMENT Application filed April 5,

This invention relates to vaporizing devices and more particularly toelectrical heating devices for vaporizing fuels for use in internalcombustion engines.

As is well known, for eflicient operation of internal combustionengines, it is desirable that the fuel be completely vaporized before itenters the combustion chambers.

It is an object of this invention to provide an attachment which may bereadily applied for use in connection with standard carburetors oninternal combustion engines.

It is a further object of the invention to provide an electrical heatingdevice for preheating and vaporizing the fuel before it enters thecombustion chambers and which may be placed in operation from a remotepoint.

These and other objects are attained by the novel construction,combination and arrangement of parts, hereinafter described and shown inthe accompanying drawing, constituting a material part of thisdisclosure, and in which Figure 1 is a side view of a carbureting device having my improvement applied thereto.

Figure 2 is a plan view showing one form of the electrical heatingattachment.

Figure 3 is a side view of the device shown in Figure 2.

Figure 4 is a plan view of another form of the electrical heatingattachment.

Figure 5 is a diagram showing the electrical connections employed.

Referring to the drawings, a carbureting device is shown at 7 and 8provided with a crank 9 for controlling a butterfly valve of the usualtype. The electrical heating attachment 10 made of suitable metal ispositioned between flange 12 of the carbureting device and flange 11 ofthe intake pipe and, as shown in Figure 2, suitable elongated apertures13 are provided so that the device 10 may be adjustably positionedrelative to the flanges and securely held thereto by means of the bolts14.

As shown in Figure 2, the heating attachment comprising an oval shapedbody, has a central aperture corresponding to the internal diameter ofthe intake pipe. A pair of electrodes 16 pass through the body 10 andSerial No. 267,558.

are insulated therefrom by the bushings 17 made from suitable insulatingmaterial. Secured to the inner ends of the electrodes 16 by means ofnuts 19 is a resistance heating coil 18, and one electrode is grounded,while the other electrode is connected to a Switch 20 and thence to thebattery 21. The switch 20 may be positioned upon the dash board of anautomobile or any other desired point.

In Figure 4 the attachment shown is similar to that described in Figure2 with the exception that the heating element comprises a crimped wire18 of high resistance instead of the heating coil 18.

In operation, when it is desired to start the internal combustionengine, the switch 20 is closed and the usual starting operations areperformed. The heating of the fuel obviously will facilitate thestarting of the engine and offers an especially desirable feature incold weather. The electrical heating attachment is superior to otherheating devices such as the use of the exhaust gases for preheating thefuel in the intake manifold. Vith the electrical heating attachmentthere is no danger of excessive heating and untimely explosions.

The foregoing disclosure is to be regarded as descriptive andillustrative onl and not as restrictive or limitative of the lnvention,

of which obviously an embodiment may be 1 constructed including manymodifications without departing from the general scope herein indicatedand denoted in the appendcd claim.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

A fuel vaporizing device for internal combustion engines comprising agenerally ovalshaped fiat metal body adapted to be secured between thecarburetor and the intake manifold of a combustion engine, said bodybeing provided with a central intake opening therethrough for thepassage of fuel to the intake manifold, apair of converging elec--trodes transversely passing through the body and extending into thecentral opening, means for insulating said electrodes from the body, acrimpe-d wire having high electrical resistance attached to theelectrodes and positioned in said central opening so that the intakefuel Will pass thereover, and elongated apertures in said body toenable. it to be adjustably positioned between the flanges of thecarburetor and intake manifold.

In Witness whereof I have affixed my signature.

ERNEST KOSANEK.
